Introduced `scope_depth` to the `Binder` to track block nesting. This
allows for correctly determining whether a `def` binding should be
`Address::Global` (at scope depth 0) or `Address::Local`.
The `type_checker` was also updated to handle `Program` and `Block`
nodes by creating a new `TypeContext` for them.
Removed the `wrap_as_lambda` method from `Environment` as the compiler
now always produces a `Program` node, effectively handling the wrapping
at the AST level. Correspondingly, `instantiate` and
`run_script_compiled` were simplified to directly run the `Program`
node.
The `instantiate` method in `Environment` has been refactored to return
`Result<Rc<Closure>, String>` instead of `Rc<NativeFunction>`. This
change separates the creation of a `Closure` from its execution,
allowing the caller to manage the `VM` lifecycle and choose the
appropriate execution strategy (e.g., single run vs. repeated benchmark
iterations).
The `NativeFunction` type is now exclusively used for true Rust
intrinsics. The benchmark runner has also been updated to reuse a single
`VM` across iterations, improving performance by avoiding repeated VM
allocations.
This commit refactors the test suite by removing the monolithic
`integration_test.rs` file.
The tests have been categorized and moved into dedicated modules within
the `tests/` directory:
- `tests/parser.rs`: Contains tests for parsing various literal values.
- `tests/destructuring.rs`: Houses tests related to destructuring
syntax.
- `tests/closures.rs`: Includes tests for closure behavior and related
optimizations.
- `tests/optimizer.rs`: Contains tests specifically targeting optimizer
logic and regressions.
- `tests/records.rs`: Holds tests for record syntax and associated
optimizations.
- `tests/rtl.rs`: Contains tests for runtime library operators and
functions.
- `tests/pipeline.rs`: Tests for pipeline functionality.
- `tests/macros.rs`: Tests for macro expansion and related issues.
- `tests/error_recovery.rs`: Includes tests for compiler error handling
and recovery mechanisms.
- `tests/examples.rs`: Verifies the execution of example scripts.
This reorganization improves test discoverability and maintainability.
The `lib.rs` file has also been updated to reflect these changes by
removing the reference to the old `integration_test` module.
The `type_checker.rs` file has had some tests removed, as they are now
covered by the more specific tests in `tests/error_recovery.rs`.
